pandas 生成并排放置的条形图和箱线图
1、代码
import numpy as np import pandas as pd import matplotlib.pyplot as plt # 生成数据,创建 DataFrame np.random.seed(27) data = np.random.rand(7, 3) index = [‘Customer ‘ + str(i) for i in range(1, 8)] Metrics = [‘Metric ‘ + str(i) for i in range(1, 4)] df = pd.DataFrame(data, index=index, columns=pd.Index(Metrics, name=‘Metrics‘)) # 设置图形属性及布局 plt.style.use(‘ggplot‘) fig = plt.figure(‘百里希文‘) axes = fig.subplots(nrows=1, ncols=2) ax1, ax2 = axes.ravel() # 在第 1 个坐标系创建竖直条形图 df.plot(kind=‘bar‘, ax=ax1, alpha=0.7, title=‘Bar Plot‘ ) plt.setp(ax1.get_xticklabels(), rotation=45, fontsize=10) plt.setp(ax1.get_yticklabels(), rotation=0, fontsize=10) ax1.set_xlabel(‘Customer‘), ax1.set_ylabel(‘Value‘) # 在第 2 个坐标系创建箱线图 colors = dict(boxes=‘DarkBlue‘, whiskers=‘Gray‘, medians=‘r‘, caps=‘k‘) df.plot(kind=‘box‘, ax=ax2, color=colors, sym=‘r.‘, title=‘Box Plot‘) plt.setp(ax2.get_xticklabels(), rotation=45, fontsize=11) plt.setp(ax2.get_yticklabels(), rotation=0, fontsize=11) ax2.set_xlabel(‘Metric‘), ax2.set_ylabel(‘Value‘) # 调整图形显示位置 fig.subplots_adjust(left=0.05, bottom=0.2, right=0.95, top=0.95, hspace=0.1, wspace=0.1) plt.show()
2 图形如下
